Loading...Adding "journaling lite'' to soft updates and its incorporation into the FreeBSD fast filesystem

Because soft updates prevent most inconsistencies, the journaling need only deal with tracking those inconsistencies that soft updates fails to address. Specifically, the journal contains the information needed to recover the block and inode resources that have been freed but whose freed status failed to make it to disk before a system failure. After a crash, a variant of the venerable fsck program runs through the journal to identify and free the lost resources. Only if a corruption of the log is detected is it necessary to run background fsck. The journal is tiny, 16Mb is usually enough independent of filesystem size. Although journal processing needs to be done before restarting, the processing time is typically just a few seconds and in the worst case a minute. It is not necessary to build a new filesystem to use soft-updates journalling. The addition or deletion of soft-updates journaling to existing FreeBSD fast filesystems is done using the tunefs program.

====================http://www.archive.org/details/dv611_carol_ruth_silver_brings_olpc_to_afghanistandv611_carol_ruth_silver_brings_olpc_to_afghanistan (2010)Christian EinfeldtAll of the video images of Afghanistan in this 6:23 video were shot by Carol Ruth Silver using an off-the-shelf consumer hand-held camera that fits in a coat pocket.

This video short tells a brief version of the story of Carol Ruth Silver's non-profit work in bringing Linux-powered OLPC netbook computers to the children of Afghanistan. The story starts at a meeting of OLPC users in San Francisco, California, where Carol is getting some help configuring her computer. She also has decided to share video with the Digital Tipping Point project, to support our effort in documenting her story. She is seen attaching her hand-held Flip video camera to a Ubuntu-Linux notebook computer owned by GNU-Linux technologist Grant Bowman, who also happens to be a technicians who is one of the backbones of the local San Francisco Bay Area Linux migration efforts that the Digital Tipping Point is documenting.

In this video, Carol tells a bit about the children she is supporting with OLPC computers. These kids don't have schools, but instead are educated in homes or sometimes outside by sitting on the ground as their lessons are read to them. Some factions in Afghanistan are opposed to educating children, thinking that a religious teaching is all that is needed for them. Sometimes their schools are blown up by these opposing factions. The beauty of using mobile OLPC computers is that they are not sitting targets for bombers, but instead move around with the kids.

Unfortunately, some of the video shot on Carol's Flip camera was corrupted, and had to be cut or truncated to remove the corrupted portions.

This video represents the first effort by the DTP crew to composite music, still images, video from other artists, along with DTP-shot video into a new composited whole. Up to this point, the 100-plus hours of video on the Internet Archive's Digital Tipping Point Video Collection has consisted of simple storyboard edited video with no music, and no contributions from other artist molded together into one complete work. Almost every movie made for the big screen since Titanic has been rendered on Linux server farms, but most of the software running on top of Linux has been non-Free proprietary applications. This video was made almost entirely with Free Open Source Software, from the capturing to the transfer to the editing and compositing and even uploading to the Internet Archive. And, of course, the Internet Archive itself runs on GNU-Linux. The only non-Free software used in making this video are the packages used for decoding and re-encoding the non-Free formats from the Flip video camera.

The Great Debate - Are We Alone? - Geoff Marcy and Dan WerthimerScience Fiction portrays our Milky Way Galaxy as teeming with advanced civilizations engaged in interstellar communication, commerce, and occasionally star wars. If so, great Galactic societies anticipate offering membership to Earth. Back in our real universe, extraterrestrial life has proved elusive. None has been found. The arguments for and against technological life in the Galaxy have sharpened in recent years. Evidence abounds on Earth of the hardiness of life even in extremely harsh environments.

Jeff is working on data quality; we may need to get new data for alpha's pointing model, but Dan isn't too worried about the inevitable small corrections. Jeff thinks the biggest data quality issue at present is Matt's radar blanking project.

Matt's been hard at work trying to figure out if there's an imperfection in our software blanking code; results from running data through the software blanker have not been matching those of hardware-blanked data. While Dan suspects that maybe the software blanker just works better, Matt and Jeff are still suspicious that the software blanker may have a bug.

Matt has the latest developments: Waterfall plots indicated that the tests he had been running were not optimal for comparing the hardware-blanker to the software-blanker, but this had the unintentional side effect of proving that the software blanker was functioning properly. Matt discovered, through a conversation with Eric, that his problems detecting artificially injected data were the result of a minor error. He is optimistic for the next week of tests.

Dan and Eric discussed adding an autocorrelation test function to SETI@home. QuothDan, "Jerry Harp believes that ET wants to broadcast a message that has a signpost (meaning it's easy to see) but also message content. These will both be in the same signal. Traditionally, you send a narrowband signal, and it's surrounded by a signal at lower power, wider band. People would see the narrowband and then they’d dig deeper and find the wideband. The problem is you have to decide how much power to put in the carrier and how much to put into the message. Jerry has another way: send a message, and a delayed copy of the message. That degrades the signal because you’re broadcasting two things at once. The way you search for it is in delay space, when you shift them you find out that they perfectly align. The idea is there’s something easy to find and then also something hard to find with content. It’s an easy thing to add and we could put it in there. It might add 5% more computation."

State of the X window, Keith Packard & Barton Massey, Google Tech Talks Feb 7 2008A few years ago, development of the X Window System was revitalized by a change in management and the rise of a new generation of machines and operating systems. This talk is a tour of X, with emphasis on the things that are new and the things that are to come: advances in 2D rendering, use of 3D hardware, high-quality typography, revamped input support, client-side migration of responsibilities, and new support for the critical layers of software between the server and the toolkit. It's the seventh Year of the Linux Desktop, and the future has never looked shinier.http://www.youtube.com/watch?v=-oFxhqYn-g0&NR=1

Packaging with version control systems A lot of Debian is already using version control for the task, but everyone cooked up something of their own, more or less. We think the situation is similar in the other distros: the current approach to package maintenance doesn't scale too well, given today's needs (teams, offline work, increasing number of users and increased use of the bug trackers), and discussions of how to improve things are on the way, but have not yet carried fruit.http://meetings-archive.debian.net/pub/debian-meetings/2008/debconf8/low/547_Packaging_with_version_control_systems.ogg

HPC clustering: Making Debian the choice for High Performance clusters and supercomputers

Enrico Zini's talk about world domination was missing an important step: clusters and supercomputers.

This keynote reports on the current state of collaboration between Debian and Ubuntu, reports back on progress made since previous DebConf's, and looks forward to new opportunities for collaboration and development.

git is a rewrite from scratch concurrent versioning system that Linus Torvalds wrote to replace cvs, subversion (svn) and other versioning systems used in large collaborative software development. Hear Linus talk about benefits of git and the drawbacks and insufficiencies that other versioning systems in common use.

I don't have time at the moment to look at specific files, but I do knowwe have many talks that were somewhat erratically cut during the liveproduction. We have not had time to go back through them and edit themtogether to get something that makes more sense. I know it's confusingand have myself been confused by it. Hopefully we'll find ways to fixthis part of the work flow to limit this mess for future events.

Sorry not to be able to be more help at the moment.
